The emotions of Canti are very human-like, despite his looks. He is embarrassed about his broken head (where Haruko hit him) and is looking for the pieces to glue back together in episode two. He wears the box on the back of his head for the same reason- shame. He is also extremely polite, extending a helping hand to Lieutenant Kitsurubami even after she attempted to destroy him.
Canti also dons a halo and fake wings (which Haruko was wearing in early episode two). Mamimi is convinced that Canti is an angel. She calls him Lord Canti after "The God of Black Flames" in a video game she plays. The rest of the cast call him by this title throughout the rest of the series. Apparently, he can also eat curry with his "mouth," but it is never really explained how.
